I am interested in the paper Enhanced Multi-attribute Combinative Double Auction (EMCDA) for Resource Allocation in Cloud Computing by Vinothiyalakshmi and Anitha (2022).

I want to implement their proposed algorithm, which is a multi-attribute combinative double auction algorithm for resource allocation in cloud computing. I am using Python as the programming language.

However, I have some difficulties in understanding and implementing the algorithm.

- how to model the customers and providers as bidders with multiple attributes, such as price, quality, reliability, etc.
- how to use the normalization factors to calculate the utility and price for each bid.
- how to find the optimal matching between customers and providers using the Hungarian algorithm.

Can anyone help me with these difficulties? How can I model the bidders, calculate the utility and price, and find the optimal matching? Any suggestions or references are appreciated. Thank you very much!
